BIO-SUPRA by LIGNA is a solvent-free monocoat oil finish that colours, protects, seals and enhances the wood grain, leaving no surface film. BIO-SUPRA is user-friendly and has no overlap effects. It’s the right choice for finishing your wood food surfaces. However, it can be used on all interior wood surfaces such as woodwork, butcher’s block, cutting boards, furniture and floors. According to the company’s research, BIO-SUPRA is the only topcoat oil certified by Health Canada’s Bureau of Chemical Safety for food surfaces. This product is frequently used in restaurants and grocery stores that require a certified solvent-free surface with zero VOC emissions.
